Twin Air Fuel Filters

You'd be amazed at the dirt and debris that can work its way into your gas can--and from there, into your fuel tank. Twin Air fuel filters with monofilament screen pockets insert in your tank to catch particles as small as 40 microns (.00165 in.) while allowing the gas to flow freely. Available for many off-road bikes and ATVs, each flange is custom-sized for each modern 4-stroke model to ensure a leak-proof seal. To clean, simply remove the filter, turn it inside-out, and clean out the debris that COULD have been in your engine. Choose the Twin Air fuel filter designed for your powersports ride.

Yuasa AGM Maintenance-Free Batteries

Yuasa AGM maintenance-free batteries have absorbed glass mat (AGM) technology. Once your battery is filled with acid, you'll never need to fill it with water or check the acid level. AGM batteries are ideal for motorcycles, scooters, ATVs, riding mowers, and personal watercraft. They feature a spill-proof design, which means there is virtually no possibility of leaks. These batteries feature advanced lead-calcium technology that pumps up starting power. AGM batteries also hold voltage longer and need less charging in standby or storage modes. This means that there will be much longer periods between charges when the batteries are used in a standby mode, like during winter storage. Yuasa batteries are available in nearly two dozen sizes and power options.

Helix Racing Products Swivel Exhaust Springs

If you like the swivel end as opposed to the fixed hook for ease of installation, replace those rusty old exhaust springs with Helix Racing Products swivel springs. They make your bike look better and eliminate worries of your exhaust falling off when landing a jump. Springs should be measured when they are off of the motorcycle, and the length measurement should be taken from inside hook to inside hook when off of the vehicle. For a correct fit, exhaust springs should not be extended more than 20 percent of their free length.
